I have the same problem, but with Beanstream:
I tried the latest x-payments on a 4.5.0 test store.
ERROR [2012-14-05 16:14:30]
User: unknown; IP: xx.xx.xx.xx
Zone: Core
Code: CURL_EXEC_ERROR (216)
CURL library: error while sending the request to remote server "
https://www.beanstream.com/scripts/process_transaction.asp". Error: "#7: couldn't connect to host"
I can process orders no problem on a 4.4.5 store without x-payments.
Thanks for any help.
